Data

The Energy Zones Mapping Tool currently includes the 322 Geographic Information System (GIS) data layers listed below. Over time, data layers will be added, updated, and removed. The GIS layers are compiled from a variety of sources for the purpose of screening-level analysis, and each has a limit to the scale, currency, and accuracy of the data.

Click any column header to sort on that column. Click the sign to view a short description of the data layer. Click on the metadata link in the table below to access metadata for each layer, and to learn more about the data quality and source. We make no warranty or representation, express or implied, as to the use, accuracy, or interpretation of the data accessible at this site.

Abstract:

The National Flood Hazard Layer (NFHL) data incorporates all Digital Flood Insurance Rate Map(DFIRM) databases published by FEMA, and any Letters Of Map Revision (LOMRs) that have been issued against those databases since their publication date. The DFIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper Flood Insurance Rate Maps(FIRMs).

Abstract:

This layer depicts aqueduct water risk results from the World Resources Institute, including water withdrawals, (total amount of water abstracted from freshwater sources for human use) consumptive use (the portion of water that evaporates or is incorporated into a product), and water supply (total blue water from natural water discharge, and available blue water which accounts for withdrawals and consumptive use).

Abstract:

This layer depicts change indicators for water supply, water demand (withdrawal and comsumptive use), water stress (the ratio of water withdrawal to supply), and seasonal variability, projected for future decades under scenarios of climate and economic growth. Time periods are centered on 2020, 2030, and 2040 for each of two climate scenarios, (RCP4.5 and RCP8.5) and two shared socioeconomic pathways, (SSP2 and SSP3).

Abstract:

This map layer contains the shallowest principal aquifers of the conterminous United States portrayed as polygons. The map layer was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series "Ground Water Atlas of the United States". This is a replacement for the July 1998 map layer called Principal Aquifers of the 48 Conterminous United States.
